Single-step electrode reactions

It should be remembered that Eq. 6E is applicable only for a single-step electrode reaction. The corresponding equation for multi step electrode reactions is Eq. 51F in Section 14.7. 

We have considered the kinetics of a single-step electrode reaction. In the case of multistep processes, the same approach is used in deriving the kinetic equations for each step. These equations, however, include the concentrations not only of the final and initial substances, but also the intermediate products participating in the various steps.
